In order to connect city infrastructure cities can use fiber optic links or wireless links depending of the capacity, length and the deployment time. This network is then the backbone upon which cities can build municipal devices, services and applications or cities can lease the capacity to other entities.
Capacity fiber optic: Very high up to 100 Gbit/s
Deployment time fiber: Low
Capacity microwave: High up to 2 Gbit/s
Deployment time microwave: Fast
